There are countless post-quantum buzzwords to list: lattices, codes, multivariate polynomial systems, supersingular elliptic curve isogenies. We cannot possibly explain in one hour what each of those mean, but we will do our best to give the audience an idea about why elliptic curves and isogenies are awesome for building strong cryptosystems.

It is the year 2019 and apparently quantum supremacy is finally upon us [1,2]. Surely, classical cryptography is broken? How are we going to protect our personal communication from eagerly snooping governments now? And more importantly, who will make sure my online banking stays secure? The obvious sarcasm aside, we should strive for secure post-quantum cryptography in case push comes to shove. Post-quantum cryptography is currently divided into several factions. On the one side there are the lattice- and code-based system loyalists. Other groups hope that multivariate polynomials will be the answer to all of our prayers. And finally, somewhere over there we have elliptic curve isogeny cryptography. Unfortunately, these fancy terms "supersingular", "elliptic curve", "isogeny" are bound to sound magical to the untrained ear. Our goal is to shed some light on this proposed type of post-quantum cryptography and bring basic understanding of these mythical isogenies to the masses. We will explain how elliptic curve isogenies work and how to build secure key exchange and signature algorithms from them. We aim for our explanations to be understandable by a broad audience without previous knowledge of the subject.

Nintendo has a new console, and it's more secure than ever.

The Switch was released less than a year ago, and we've been all over it. Nintendo has designed a custom OS that is one of the most secure we've ever seen, making the game harder than it has ever been before. In this talk we will give an introduction to the unique software stack that powers the Switch, and share our progress in the challenge of breaking it. We will talk about the engineering that went into the console, and dive deep into the security concepts of the device. The talk will be technical, but we aim to make it enjoyable also for non-technical audiences.

This talk will give a unique insight of what happens when consoles have been hacked already, but not all secrets are busted yet. This time we will not only focus on the Nintendo 3DS but also on the Wii U, talking about our experiences wrapping up the end of an era. We will show how we managed to exploit them in novel ways and discuss why we think that Nintendo has lost the game.

As Nintendo's latest game consoles, the 3DS and Wii U were built with security in mind. While both have since been the targets of many successful attacks, certain aspects have so far remained uncompromised, including critical hardware secrets. During this talk, we will present our latest research, which includes exploits for achieving persistent code execution capabilities and the extraction of secrets from both Wii U and 3DS. Basic knowledge of embedded systems, CPU architectures and cryptography is recommended, though we will do our best to make this talk accessible and enjoyable to all. We also recommend watching the recording of last year's C3 talk called "Console Hacking - Breaking the 3DS".
